Core dump, bus error, byte alignment, ObjStack

aspell-0.60-20040511 fails on Sparc architecture (big endian). The 
failure occurs here when building the dictionaries:

#0  0xff228bac in (anonymous 
namespace)::create(acommon::StringEnumeration*, aspeller::Language 
const&, acommon::Config&) (els=0x5e6f0, lang=@0x60888, config=@0x60070) 
at modules/speller/default/readonly_ws.cpp:855
#1  0xff229f34 in 
aspeller::create_default_readonly_dict(acommon::StringEnumeration*, 
acommon::Config&) (els=0x5e6f0, config=@0x60888) at 
modules/speller/default/readonly_ws.cpp:1107
#2  0x00029efc in master() () at prog/aspell.cpp:1333


The problem is the misalignment of 'b' as produced 2 lines above by:
          WordData * b = (WordData *)buf.alloc(total_size);


A simple workaround which so far has allowed aspell to run is to modify 
ObjStack alloc(size_t size) to align to a 4 byte boundary:
